I’m Looking For Koi Fish Dataset At Least 10000 Images

I have this thesis about koi fish counting and classification, the document was accepted, however, I find trouble finding the number of datasets required by our professor for the implementation part. Let’s say around 10,000 images of koi fish would suffice.

I appreciate any help that I can get, since my current dataset only ranges around 1200 which are already classified and annotated which I’ve sourced from Kaggle and Roboflow. Thanks. (I’ll be using YOLOv9 for the model to be trained)

P. S. Don’t mind the link.
